Appl. No.:

10/222255

Assignee:

Communications & Power Industries, Inc. - Beverly MA

International Classification:

H05B006/70

US Classification:

219690, 219756, 333248, 137252

Abstract:

A waveguide system for passing microwave energy while blocking foreign particles from a moving gas passing through the system is provided. The system includes first and second waveguide sections and a low loss microwave window disposed between the waveguide sections to allow microwave energy to pass from the first waveguide section through the window to the second waveguide section. The system also includes a gas bypass filtration system having a first port in communication with the first waveguide section, a filter element in communication with the first port, and a second port in communication with the filter element and with the second waveguide section. The system of the invention having these features blocks, by means of the window, a gas flowing through the first waveguide section and forces that gas to flow through the gas bypass filtration system so that it enters the second waveguide section only after passing through the filter. A system designed to include a pillbox window is also provided.

International Classification:

B07C 510

US Classification:

209525

Abstract:

An apparatus for receiving and handling empty beverage containers. The empty containers may be received either individually or in cartons upon a moving conveyor. An alignment mechanism separates the containers and moves them to one side of the conveyor. A switch arrangement senses cartons, so that the system can process cartons of empty containers in a different manner than individual empty containers. The containers, whether individually or in cartons, pass through an illumination station wherein they interrupt illumination falling upon a row of photocells. Output signals from the photocells are transmitted to identification circuitry together with clock signals generated in synchronism with the movement of the conveyor. The identification circuitry generates registration signals, which are used to compute value of the containers being received. A paddle mechanism shifts the cartons to a separating station, which forwards properly filled cartons to a storage area.
